BEARD TRIMMER HAVING ONE OR MORE ROTARY HEADS

Abstract

The present invention relates to a beard trimmer having one or more rotary cutting heads having a moving blade and a fixed blade, each head being surrounded by a telescopic comb in the form of a crown, said comb being height adjustable and making it possible to adjust, in use, the distance between said blades and the skin and thus to set the cutting of the beard hairs to the desired length.

Description

BRIEF DESCRIPTION OF THE FIGURES

[0017] FIG. 1 shows a beard trimmer according to the invention comprising three rotary heads. The crown-shaped comb around the rotary heads is shown with three different adjustment heights. These three adjustments for example make it possible to obtain hair lengths of 2, of 6 and 10 mm.

[0018] FIG. 2 shows a beard trimmer according to the invention with an alternative where a spacer in the form of a central stop has been added. The spacer is adjusted to the same height as the combs shown in three different positions. The spacer has the same function as the combs, i.e., maintaining the distance between the cutting mechanism and the skin.

[0019] FIG. 3 shows a detailed view of a cutting head in its version with a central spacer, and with several adjustment heights of the comb. The figure makes it possible to respectively distinguish the cutting lengths of the beard hairs that these positions make it possible to obtain. The presence of a spacer allows the greatest precision for cutting lengths between 2 and 6 mm.

[0020] FIG. 4 shows a view similar to FIG. 3, but in an embodiment with no central spacer.

[0021] FIGS. 5a and 5b schematically show two different views of the height-adjustment mechanism of the combs. The translational movement of the combs can be done manually by pressing a slide-type button, or can be motorized (not shown).

[0022] FIG. 6 shows a three-dimensional view of the trimmer according to the invention with its removable cover making it possible to facilitate cleaning of the cutting mechanism.

[0023] FIG. 7 shows a planar view of part of the cutting mechanism and crown-shaped comb.

[0024] FIG. 8 shows an exploded view of the cutting head of the trimmer according to the invention, in particular with a spring making it possible to push the moving blade against the fixed blade.

[0025] FIG. 9 shows a detailed view of the mechanism according to which the hairs are cut by the cutting head of the device according to the invention.

[0026] FIG. 10 shows the movement of a cutting head in use with two different cutting heights.

[0027] FIG. 11 shows an exploded view of an embodiment with three heads of the trimmer according to the invention with all of the component elements.

[0028] FIG. 12 shows embodiments of the trimmer according to the invention with one and two rotary cutting heads.

DETAILED DESCRIPTION OF THE INVENTION

[0036] Unlike the beard trimmers of the state of the art, the trimmer according to the present invention has one or more circular rotary heads 1 with a vertical axis, surrounded by crown-shaped combs 4, the height of which can be adjusted to within a millimeter. This adjustment can be manual or motorized (not shown). This trimmer allows an arcuate movement over the beard, like a razor with rotary heads. This type of movement has the advantage of starting trimming of the hairs on all sides, irrespective of the incline thereof relative to the skin, which results in a uniform trim of the beard.

[0037] The movement of the combs 4 stands up the hairs, which ultimately penetrate from the outside toward the inside via the space left free between two teeth in the trimming zone. The particular shape of the teeth of the comb 4, which gradually become thinner toward the tip, allows easy penetration of beard hairs toward the trimming element made up of a fixed blade 3 and a moving blade 2.

[0038] The fixed blade 3 comprises radial notches, which also favors the penetration of hairs in the cutting mechanism.

[0039] The height of the telescopic combs 4 can be adjusted approximately between 0 and 15 mm, preferably between 0 and 12 mm, and particularly preferably between 0 and 10 mm. The combs are therefore completely retractable in the cover 6 to take up less space when the trimmer is stowed. This is the only interest of the adjustment to 0 mm, since a razor would of course be more suitable for simply shaving the hairs to a length of about 0 mm.

[0040] The cover 5 surrounding the rotary head(s) is removable to facilitate cleaning of the cutting mechanism. FIG. 6 shows the removal of the cover 6. This function is important inasmuch as beard trimming, which is often only done once or twice per week, generates significantly more cutting waste than simple shaving.
